Extracted text: 8. The gas constant of CO2, N2, He are 0.1889, 0.2968, and 2.077 KJ/kg-K respectively. The three are mixed with 0.4 kg CO2, 0.7 kg N2, and 0.05 kg He. The mixture has a temperature of 35°C and pressure of 180 kPa. Calculate the volume of the mixture in cubic meter.


Extracted text: 7. Two vessels 1 and 2, of different sizes are connected by a pipe with a valve .Vessel contains 142 L of air at 2,767.92 kPa, 93.33°C. Vessel 2 of unknown volume contains air at 68.95 kPa, 4.44°C. The valve is opened and when the have been determined it is found that the pressure of the mixture is P3 = 1378.96 kPa and the temperature of the mixture is T3= 43.33°C. How many liters of air are contained in vessel 2?
